DPF Delete Kits

Yes—if not tuned. All DPF delete kits must be paired with proper ECU tuning. Without it, your truck may enter limp mode or show engine warning lights.

Yes. High soot load, excessive differential pressure, failed regen, or sensor faults can trigger derate or limp mode. Read the codes and live data before replacing parts.

Deleted-and-tuned off-road builds may improve throttle response, exhaust restriction, EGT control, and fuel use. Some owners discuss ranges like +35 to +120 HP, 100°F to 300°F lower EGT, or +1 to +3 MPG, but results depend on the truck, tune, load, altitude, and supporting mods.

We offer fast shipping across the U.S. and Canada, typically within:

Use our vehicle filters or consult our support team. You’ll need to know:

• Engine type (e.g., 6.7L Cummins, LML Duramax)
• Model year (e.g., 2011–2023)
• Cab/chassis or pickup body type
• Inlet size preference (4" or 5")

We're happy to help confirm fitment before you order.

Most diesel trucks take 20–45 minutes to complete a DPF regen. It usually happens every 300–500 miles, depending on driving conditions.

With a SPELAB DPF delete kit and proper tuning, regen cycles are fully eliminated, improving power and fuel efficiency.

The total cost typically ranges from $1,000 to over $3,500, depending on your vehicle and the method used. A basic delete pipe kit starts around $500–$800, but you will also need a tuner (essential to prevent error codes), which adds $500–$1,500. Professional installation labor generally costs between $500 and $1,500. For a detailed breakdown of parts, labor, and tuning fees, read our full guide on the cost to remove a DPF.

No. It can reduce restriction in the removed aftertreatment section, but it will not fix bad injectors, turbo issues, boost leaks, fuel delivery problems, or weak engine compression.

The usual causes are wrong cab or bed configuration, pickup versus cab-and-chassis mismatch, loose factory hangers, twisted clamps, or tightening one section before the full system is aligned.

No for emissions-controlled street use. Removing or disabling emissions equipment is not legal for public-road vehicles in the United States.
